LOCK FOR DEMOUNTABLE RIMS.

Specification of Letters Patent. Patented 'Da i7, 1918.

Application tiled July 7, 1916. Serial No. 108.019.

To Il wlw/11 it ymay concern.'

Be it knownxthat 1,' OLIVIER La BEAU, a subject of the King of GreatBritain, and resident, of the city of ll/ontreal,l Province ot' Quebec,anada, have invented certain .new and useful improvements in Locks forDemountable Rims; and do hereby declare that the following is a full.clear, and exact description of saine.

This invention relates to devices for re- 'leasably lockingcle-mountable rims` for wheels of automobile and other vehicles, inposition upon the wheel.

An object of the invention is to provide an improved device for lockingthe rim in place and one which is more readily op erated and convenientthan those heretofore in use.

For full comprehension` however. of my invention reference should be hadto the accompanying drawings forming a part of this specification. inwhich similar reference. characters indicate the same parts 'and whereinl4`ig. 1 is a segment ot' a wheel with my improved rim and lock appliedthereto; and

Figs. 3 and l are enlarged transverse sections through the rim andJr'elly and illustrating successive positions otthe lock.

Referring now to the drawings 2 indicates` the t'elly of a wheel and 2the metallic band fixed thereon. such band carrying at one side theannular outwardly extending stationary flange 3 between which anddisplaceable locking means the demountable rim t is clamped and held inplace as is usual with dcmountable rims.

My improved displaceable locking means consists ot' a suitable number oflocking elements spaced around the wheel and, each consist-ing of alever 5 plvotally mounted at one end to the wheel and a rim engaging]a\'v,6 pivoted to the. lever eccentrically with respect to the pivotalmounting of the latter.

In order that the rim lock can be applied to wheels of usualconstruction and so avoid the necessity forispecial construction I havemounted the lever 5 between spaced arms 7 of a U-shaped bracket 8 whichlatter is conveniently mounted upon the slide of the felly by means of abolt 9 and nut 10, the bolt being 'accommodated in the transverselyextending' hole 11 usually found in the felly for the reception of thebolt which attaches the rim lock in use at the present time. The

U-bracket lits fiat against the telly with the arms 7 extendingoutwardly and having the pivoted inner end of the lever 5 carriedtherebetween. such pivoted end being forked to form spaced lugs 12between which the inner end of jaw 6 is accommodated and the pivotalconnection between lever and bracket arms being formed by studs 13,which are in screw-threaded engagement with the arms 7 and extendinwardly therefrom and loosely into the lugs 12 to form trnnnions forthe lever. The inner end of the jaw 6 is pivoted to the lugs 12 by a pin1-lwhich passes through the jaw and is carried by the lugs at a pointradially disposed with relation to the studs 13, it being pref ferredto'arrange this eccentrically disposed pivot pin l-l between the inneror pivot end of the lever and the studs. that is to say ori the oppositeside of the studs to the free or outer end of the lever.

As seen in dotted lines Fig. 2, the lever and jaw can be swung inwardlywithin-the f elly to permit of an unobstructed applica-k tion of the runand then as shown in full lilies in such figure swung `to bring the jawinto engagement with the edge of the rim,

therim engaging end of the jaw being concaved at 15 in generalconformity with the curvature of the rim edge to insure a .snugrengagement therewith and serrated to avoid any tendency to slip. oneside of the jaw being constituted by a wedge Vshaped lip 16 adapted toenter beneath the rim.

ly swinging the outer or t'ree end of lever 5 inwardly from itspreliminary outwardly extending osition illustrated in full lines Fig.2. to t e inwardly extending position Fig. 3. the pivot pin 14 is movedin an arcl toward the rim in the radial line of the wheel and outwardlyfrom the rim in the axial plane of the wheel as indicated by arrow Fig.3, the radial movement reducing the distance between the studs 13 andrim and thus springing or stretching the latter tightly around the.felly and the movement in the axial plane swinging the inner end of thejaw outwardly and consequently swinging the outer or, rim engaging endinward y to force the rim tightly against the stationary flange 3 and.wedge the lip 16 beneath the' rim and tightly secure the rim upon thetelly. When as shown in Fig. 4, the lever has been swung inwardly as faras pos-v sible that is when its free endengages the underside of thefelly, the pivot 14 has been forced outwardly in the axial line of thesovl l the inner side of the rini and tion to studs l3and consequentlyuntil released b f the outward si'in'in or" the lever the jaw is lockedin its engagement with the rim because continued outward movement of thepivot 14y is prevented by the stalling of the free end of the leveragainst the felly While inward movement dead centeregain. is preventedby the inward pressure of the rim due to its previous stretching. WhileI have illustrated a novel vtwo-part rim l do not herein describe orclaim same as it forms the subject matter of a divisional applicationtiled by myself.

What I cla1n1 is as follows:

l. In combination, a Wheel, a demonntable rim for the Wheel, lockingmembers adapted vto engage the rim and levers respectively pivoted 'tothe members for moving 'saine outwardly in the radial line of the wheeland inwardly in theaxial plane of the Wheel.

2. In combination, a Wheel, a deinonntable rim for the Wheel and devicesfor locking the rini upon the wheel, each of said devices including alever pivotally mounted near one end upon the Wheel and a rim engagingjaw pivoted `to the lever between the pivot of the latter and the pivotend of saine.

3. ln combination, a Wheel, a denlountable rim for the Wheel and devicesfor locking 'the rim upon the wheel, each of said devices includingr a.lever pivoted to the Wheel, a member pivoted to the lever at a pointdisposed' eccentrically Vith relation to the pivot of said lever, suchmember being adapted .in its locking position to engage have its pivotpoint disposed o dead center position with relation to the pivot of thelever and on that side of such pivot which is outward in the axial planeof the Wheel.

4. In combination, a wheel, a demonntable rim for the wheel,.rim lockingmembers each of which has a tapered lip adapted to enter beneath `therim and levers respectively pivoted to said' members and adapted tonieve the same outwardly in the radial line of such pivot past -the rim,serrated and presenting Qf the wheel and inwardly in the axial plane 0fthe Wheel.

5. In combination, a wheel, a demountable rim for the Wheel and riinlockingr devices cach including a braekct carried by the felly, 'a leverpivoted vabone-end to the bracket and a rim-engaging jaw pivoted to thelever atza point between the pivot of the lever and the pivot end ofsuch level', the free Vend of the jaw being concaved in generalconformity with the rini and presenting a tapered lip adapted to enterbeneath the rim.

In combination, a wheel the telly of which hasholes extendingtransversely therethrough, a dcnionntable rini for the wheel and rimlocking devices each including a U-bracket, a bolt passing through oneof said holes in the felly and attachingr the bracket to the latter, anut securing the bolt,v a lever pivoted at one end between the. arms ofthe bracket and a rim engaging jaw pivoted to the lever at 'a pointbetween the pivotof the lever and the pivot end of such lever, the freeend of the jaiv` being concaved in general conformity ywith a taperedlip adapted to enter beneath the rim.

7. In combination, a wheel, the folly of which has holes extendingtransversely therethrough, a demountable riin for the wheel and rin!locking devices each including a U-bracket, a -bolt passing' through oneot said holes in the felltv and attaching the bracket to the latter. anut. securing the, bolt, a forked lever, studs in screwthread edrelation with the arnis of the U-bracket and loosely entering the sidesof the lever near its forked end, and a riin engaging jaw pivoted to thelever within its forked end at a point between the studs and tbe pivotend of such lever. the tree end ot' the jaw being concaved in generalconforniitv 'with the rim, serrated and presenting a tapered lip adaptedto enter beneath theu'im. in testimony whereof, l have signed nl v naineto this specification.
